BackgroundCancer cachexia is a complex syndrome characterized by an ongoing loss of skeletal muscle mass and progressive functional impairment. A proactive management approach is recommended, including physical exercise to maintain function via modulation of muscle metabolism, insulin sensitivity and levels of inflammation. The review aimed to determine the safety, acceptability and effectiveness of exercise in adults with cancer cachexia. Secondary aims, subject to the data availability, were to compare effectiveness according to the characteristics of the study intervention or population.MethodsWe sought randomised controlled trials (RCTs) in adults meeting international criteria for cancer cachexia, comparing a programme of exercise as a sole or adjunct intervention to usual care or an active control. CENTRAL, MEDLINE, EMBASE, DARE and HTA, ISI Web of Science, LILACS, PEDro, SciVerse SCOPUS, Biosis Previews PreMEDLINE and Open Grey databases were searched up to June 2014. Two authors independently assessed studies for eligibility.ResultsWe screened 3154 separate titles and abstracts, and reviewed 16 full-texts. Corresponding authors were contacted to determine if samples met cachexia staging criteria. Most authors did not explore this concept. No trial met review eligibility criteria. We were unable to perform a meta-analysis to determine any effects from exercise intervention.ConclusionDespite a strong rationale for the use of exercise, there is insufficient evidence to determine safety and effectiveness in patients with cancer cachexia. Findings from ongoing studies are awaited. Assessment of cachexia domains, ideally against international criteria, is required for future trials of exercise and supportive care interventions.

Exercise intervention proved to be better than not exercising. CT was better than RT in improving HRQoL.

There is insufficient evidence to determine the safety and effectiveness of exercise for patients with cancer cachexia. Randomised controlled trials (i.e., preferably parallel-group or cluster-randomised trials) are required to test the effectiveness of exercise in this group. There are ongoing studies on the topic, so we will update this review to incorporate the findings.

The evidence shows that pilates or home-based exercise should be encouraged to women with breast cancer.

Background Acute respiratory infections (ARIs) last for less than 30 days and are the most common acute diseases affecting people worldwide. Exercise has been shown to improve health generally and may be effective in reducing the occurrence, severity and duration of acute respiratory infections. Objectives To evaluate the effectiveness of exercise for altering the occurrence, severity or duration of acute respiratory infections.
